Fitment: This kit is specifically designed for 2015 - 2021 Subaru WRX models. Features: The Turbo XS Boost Control Solenoid replaces the factory 2 - port solenoid with a 3 - port one. It's essential for excellent boost control when using an aftermarket front pipe on your WRX.


How to use: First, make sure your car is turned off. Locate the factory 2 - port boost solenoid and carefully remove it. Then, install the Turbo XS 3 - port boost control solenoid in its place, following the included instructions. Attention: When installing, ensure all connections are secure to prevent any air leaks. Also, don't try to install it if you're not familiar with car parts. Maintenance: Regularly check the solenoid for any signs of damage or wear. Clean it gently with a soft cloth if it gets dirty. This will help keep it working well and extend its lifespan.
